Operating Instructions

Control via two different-shaped buttons: power button (ON/OFF and intensity adjustment) + MODE button (temperature and light source switching)

Power ON/OFF: When the light is off, hold the power button for 1 second to access neutral white light LOW. When the light is on, hold the power button or MODE button for 1 second to turn it off.

Primary white light: From LOW, press the power button briefly to cycle through levels: LOW - MID - HIGH.

Color temperature switching: When white light is on, press the MODE button briefly to switch between neutral white light (4500K), warm (3000K) and cool (6500K).

Direct ULTRALOW access: When the light is off, press the power button twice.

Auxiliary red light: When the light is off, hold the MODE button for 1 second to access red light LOW. Press the power button briefly to switch from Red LOW to Red HIGH.

Special modes (SOS/Beacon/Slow Flash): In any state, press the MODE button twice to access SOS mode. Press the power button briefly to cycle through: SOS - BEACON - SLOW FLASH.

Lock/Unlock: When the lamp is off, hold both buttons for 2 seconds until the lamp flashes 3 times (locked). To unlock, hold both buttons again for 2 seconds until neutral white ULTRALOW light activates.

Battery indicators: When the light is off, press the MODE button briefly to display charge level via 4 indicators (4 constant = 75-100%, 3 constant = 50-75%, 2 constant = 25-50%, 1 constant = 0-25%).
